so since i haven't been able to sell off my crystal PROst subwoofers... i thought why not, maybe i should try to design a ported box for it. I am completely clueless as to how to design one but through a lot of searching i came up with this:

http://www.caraudio.com/gallery/2/7/2/2/0/crystalbox.JPG

i was looking for 6.5 ft^3 @ 29 and the dimensions would fit perfectly into my trunk, any bigger i cannot work with. now am i close to something that would work? or am i completely off and need to find someone to design a box for me?

this box is for 4 12" crystal mobilesound PROst subwoofers.Sorry for the horrible MSpaint skillz and i'm sure there are many opportunities for mistakes because i did all the calculations by hand. :crazy:

all input is greatly appreciated.
